To be frank

I find the lane departure alert while on ramps and sensor failure warnings for the pre-collision system in heavy rain more distracting than using the voice controls. And since it's a limited set of instructions, and leaves my hands on the wheel and my eyes on the road, it is less man machine interface distracting than tuning the old dial or push button radio. The instruction set is more concise than "Honey, can you put a different station on?" Now, there may be some higher "non-human" communications cerebral load involved compared to conversing with a seat mate, and you don't have the second set of "Hey watch out " eyes, but I've found the voice controls (and or the single button presets) to be less distracting than the manual controls for the cockpit of my older cars)
The one automation I've been trying and am about to ditch is the high beams. I think I can do a better job than that thing.
